[Use of the pepsinogen-pepsin test in examining persons at high risk of stomach cancer].
The paper deals with the description of a simple, time-saving and sufficiently precise procedure of determining the activity and level of pepsinogen-pepsin in the gastric juice of healthy subjects and those at high risk for stomach carcinoma by means of photography. The level of pepsinogen-pepsin in the gastric juice of stomach cancer patients is generally found to be very low or nil. A considerable drop in the enzyme's activity is also observed in cases of polyposis of gastric mucosa as well as in ana- and hypoacidic states. The procedure may be used for assessment of the secretory function of gastric mucosa and screening for groups at high risk for stomach carcinoma.
